Numark CDN77usb Manual 

This guide will take you through a couple of the functions and best practice in using the Numark CDN77USB CD and MP3 player at FromeFM. There have been a number of reports recently about the CD player acting up. This is due to the amount of usage it gets and affects the left deck more than the right as it gets more usage. It is likely that the left laser has become defocused which is why it often works fine for professionally produced CDs but not ones made at home. We will be replacing it soon but in the mean-time we are keen to ensure that no presenter is struggling to play a track on air. The most efficient, quick and simple way to play music on FromeFM is use to MP3 files added to a USB stick. Using a USB stick means you don’t need to keep opening and closing the tray to change CDs and you are able to use both the left and the right deck from the same USB meaning you can do your entire show from a single USB. First things first, you will need to convert the songs for your playlist into MP3 files. It is crucial that the files are MP3 and not .M4A (iTunes), .WMA (Windows Media) or any other format including .WAV .OGG .AAC etc.

MP3 files from CDs or you can purchase them from digital media stores, or download from Soundcloud/Bandcamp etc. Once you’ve got all your music ready it’s time to copy them onto whatever USB stick you intend to use. We recommend that you use one USB stick solely for use in the player rather than a general use one that also includes other files such as Word files, Excel or images. If you want to you can sort the files into named folders. This is useful if you want to plan several shows in advance, or if you want to put a large number of files onto the USB from different artists and albums and want to flick between them like you would a CD changer. Now we come to the fun part of actually getting these files into the memory of the audio player and through the desk. Pop the USB into port A or B, it doesn’t really matter. Port B is slightly easier to get the stick into as its lower and not as close to the edge of the rackmount.

so it’s useful to ensure every track has a title then you can see it on the screen. The audio player will generate the track numbering based on the filename of each track. I tend to then rename the files by preceding it with a track number. E.g. 01 Abba – Mamma Mia.mp3 02 Military Wives charity single.mp3 03 Adagio in D Minor (John Murphy).mp3 Sometimes the audio player will automatically detect the presence of the USB and switch focus to it but this isn’t always the case. It’s easy to switch sources though simply click on the “Source” button to switch between CD, USB A and USB B.

memory of the CD player. If you are using multiple folders then you may need to find the relevant location by pressing the folder button and using the twisty knob to locate the right place. Press the knob in to select the folder. Press the folder button to go back up a level. Once you’ve selected your folder (or you are staying in the root of the USB) you are ready to select your tracks. You can use the same source and folder controls on the other deck of the player as if it were a different CD meaning you can have one folder on the left side and a different one on the right for example. Simply use the normal track changing knob to skip forward and back through the tracks. They will be in the same order as the filename you put them on the stick with. Tap the Play button as normal to play. All the other controls are identical to using CDs.

If you don’t have the audio files as MP3 then where possible please use original CDs rather than burned CDs/CD-Rs. CD-Rs have thinner surface layers for data storage and are more susceptible to damage and scratches. When the laser is slightly out of alignment (as is the case in the left deck right now) or if there are micro scratches on the surface, the audio player can have difficulties. If you really MUST use burned CDs though please try these tips: • Make sure you are using a single use CD-R rather than a rewritable CD-RW. • Make sure the disc is “finalised”, this means you cannot burn anything else onto the disc after the original burn. • Make sure you are burning as "Audio CD" format not DATA. • If neither of the above works, it may just be that the brand of CD-R disk you are using does not work well with the audio player. This happens sometimes with budget discs. Try a different brand. Cheaper white labelled brands have more trouble than established brands like Sony or Memorex. • Burn at a slower speed! Try burning a disk at 1x (rather than 4x or 8x or whatever speed your burner drive supports). Very often audio CD's burned at slower speeds will work in audio players while discs burned at higher speeds won't. It's been said that the laser encoding is somehow "clearer" when burning at slower speeds and this helps audio players, which often have a problem with home-burned CD's, to cope with the discs. • Ensure you record all your audio CD's in "disc at once" mode, meaning the whole disc is burned in one pass without turning off the laser. Audio players like discs burned like this better. If you burn the disc "track at a time" the laser is turned off between each track, and audio players often cannot find any track other than the first one on such disks. • If all this fails use the Laptop to play CD’s.
